تهیه کمپلکس های cr(iii) و zn(ii) با لیگاند آنتراکینون با استخلاف وینیلی

abstract the cr(iii) and zn(ii) complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl)benzoic acid as ligand have been prepared by reacting cr(no3) and zn(no3)2 and ligand in cloroform. the cr and zn complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl) were also prepared in chloroform and aceton solutions. the uv-visible and ft-ir spectra of all the complexes were studied. the investigations suggest that zn and cr complex the oxygen atoms of ligands are linked to central metal atom. in this experiment, all the ligands were prepared and characterized by ft-ir and uv-visible spectra.
